Abstract

L'invention concerne un dispositif émettant de la lumière dans lequel une couche de conversion de couleur est formée mince, tout en réduisant une non-uniformité de couleur. L'invention concerne spécifiquement un dispositif émettant de la lumière (10) qui comprend une puce DEL (11) et une couche de conversion de couleur (10) qui est formée sur la surface supérieure de la puce DEL (11) et faite d'un matériau transmettant la lumière contenant un luminophore qui est excité par la lumière émise par la puce DEL (11) et émet de la lumière ayant une longueur d'onde plus grande que la lumière provenant de la puce DEL (11). La surface supérieure de la puce DEL (11) comporte une électrode de type cadre (11a) le long d'une périphérie externe entière de la puce DEL (11), et la couche de conversion de couleur (12) est formée sur la surface supérieure de la puce DEL (11) dans la région entourée par l'électrode de type cadre (11a).
